I just bought an ATV2 a week ago and while watching Netflix the TV speakers output a pop/crackle/static every few minutes or so. This has never happened on any other of my components so I assume it has got to be the ATV2 or a very rare chance of being the HDMI cable that I have not used in a year or so. Has anyone had this problem and is it fixable or do I have a bad device? Thanks!!!
